预抽煤层瓦斯穿层钻孔有效影响半径是实施科学治理瓦斯的基础,以淮北集团邹庄煤矿煤层地质为研究背景,采用压降法对矿井四采区72和82煤层进行瓦斯穿层钻孔有效影响半径的测试,并利用Origin对穿层钻孔有效影响半径与抽采时间的变化关系进行分析,得出穿层钻孔有效影响半径与抽采时间的函数关系式.结果表明:预抽时间为1,2,3个月时,72煤层穿层钻孔有效影响半径分别为3.0,3.5和4.0 m,82煤层穿层钻孔有效影响半径分别为2.5,3.0和3.5 m.分别以4.0和3.
Let R be an associative ring with identity,and Y be a class of right R-modules,which contains all injective right R-modules.In this paper,we introduce the definition of Y-Gorenstein cotorsion modules,which is a generalization of cotorsion and Gorenstein c
Let G=(V,E)be a graph.For a vertex labeling f:V→Z2,it induces an edge labeling f+:E→Z2,where for each edge v1 v2∈E we have f+(v1 v2)=f(v1)+f(v2).For each i∈Z2,we use vf(i)(respectively,ef(i))to denote the number of vertices(respectively,edges)with label i
In this paper,we study the blow-up of solutions to a semi-linear wave equation with a nonlinear memory term of derivative type.By using methods of an iteration argument and di erential inequalities,we obtain the blow-up result for the semi-linear wave equ
为确定沿空掘巷窄煤柱合理宽度,基于实际地质条件,运用现场试验、理论计算和数值模拟相结合的方法对薛湖煤矿2306运输巷侧帮预留窄煤柱合理宽度进行研究,结果表明:2306运输巷侧帮卸压带宽度为9~10 m,封孔深度为10 m时可实现瓦斯的连续性性抽采.煤柱宽度为3~5 m时煤柱被塑性区贯通承压能力差;煤柱宽度为5~7 m时煤柱内部出现“弹性核”,煤柱强度足以承载上覆岩层载荷;煤柱宽度为7~9 m时煤柱内部“弹性核”开始向采空区侧转移.随着煤柱宽度增加,煤柱向两侧的水平位移也逐渐增加,且对采空区的影响小于对煤巷
研究井田瓦斯分布规律对矿井瓦斯灾害防治和煤矿安全生产具有十分重要的意义.以湖南上二叠统龙潭组为研究对象,选取相对瓦斯涌出量、瓦斯含量、矿区内突出矿井百分比等瓦斯地质技术参数,采用平面图参数对比方法,对比分析煤田地质技术参数,如沉积总厚度、砂泥比、含煤层数、可采煤层累计厚度等的关系.结果显示:湖南龙潭组的瓦斯灾害与三角洲沉积体系的关系密切,但不同类型的三角洲具有不同的影响程度;瓦斯灾害程度与其沉积速率具有负相关,也即沉积速率越大,瓦斯灾害越轻.研究表明瓦斯灾害程度与煤田地质技术参数一样具有区域分布特性,需要
Based on the multivariate mean-shift regression model,we propose a new sparse reduced-rank regression approach to achieve low-rank sparse estimation and outlier detection simultaneously.A sparse mean-shift matrix is introduced in the model to indicate out
In this paper,we consider the initial-boundary value problem for the large scale three-dimensional(3D)viscous primitive equations under random force.Assuming that the random force and the heat source satisfy the some assumptions,we firstly establish rigor
In this paper,we give a necessary and sucient condition for a strongly pseudoconvex complex Finsler metric to be locally conformal pseudo-Kahler Finsler.As an application,we nd any complete strongly convex and locally conformal pseudo-Kahler Finsler ma
